Indigenous peoples are crucial for conservation – a quarter of all land is in their hands.

Posted on Aug 03, 2018

Indigenous peoples have a deep and unique connection to the lands they inhabit. This connection has persisted throughout the world, despite centuries of colonisation, displacement and suppression of their cultural identities.

What has never been appreciated is the contemporary spatial extent of Indigenous influence – just how much of Earth’s surface do Indigenous peoples still own or manage?

Given that Indigenous peoples now make up less than 5% of the global population, you might imagine the answer to be “very little”. But you would be wrong.

In our new research, published in Nature Sustainability, we mapped Indigenous lands throughout the world, country by country. We found that these covered 38 million square kilometres – about a quarter of all land outside Antarctica.

Some 87 countries around the world, on every inhabited continent, have people who identify as Indigenous and contain land that is still owned, managed or influenced by Indigenous people.

These areas are very valuable for conservation. About 65% of Indigenous lands have not been intensively developed, compared with 44% of other lands. Similarly, just 10% of the world’s urban areas, villages and non-remote croplands are on Indigenous peoples’ lands.

By contrast, Indigenous lands encompass nearly two-thirds of the world’s most remote and least-inhabited regions. These are the places with the lowest levels of built environments, crop land, pasture land, human population density, night-time lights, railways, roads and navigable waterways.

An incredible 40% of lands listed by national governments around the world as being managed for conservation are Indigenous lands. Some of this has official recognition. For instance, Australia would never meet its promises under the Convention on Biological Diversity if its Indigenous peoples had not been prepared to allocate more than 27 million hectares of their land to conservation.

Yet there is danger in making assumptions about the aspirations of Indigenous peoples for managing their lands. Without proper consultation, conservation projects based on Indigenous stewardship may be unsuccessful at best and risk perpetuating colonial legacies at worst.

Conservation partnerships will only be successful if the rights, knowledge systems and practices of Indigenous peoples are fully acknowledged. Many Indigenous peoples have acknowledged this fact, by calling for partnerships that respect, understand and follow local processes. There is no one size that fits all – Indigenous peoples are hugely diverse.

Indeed, so important are local perspectives to Indigenous relationships with land that we pondered for a year on the ethics of creating a global map. However, we also felt that the story of enduring Indigenous influence needs to be told. Our final map shows that broad swathes of Asia, Africa, the Americas, Australia and the far north of Europe are Indigenous lands.

Adapted from Garnett et al. 2018.On every inhabited continent there is a significant overlap between Indigenous management and natural lands.

Our results are particularly important at this time when goals for sustainable development after 2020 are being developed. The results also feed into assessments by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the international body that assesses the health of the world’s wildlife diversity and ecosystems. It is much more than biodiversity that relies on Indigenous management of land. So too do many of the ecosystem services that allow humans to thrive.

Finally, we should note that, for many countries, the areas we have mapped are the minimum – further work will almost certainly discover that Indigenous influence extends far further than is currently acknowledged.

Yet our crucial message remains the same: that Indigenous peoples hold the future of much of the world’s wilderness in their hands.
